Semi-Leptonic Decays in Lattice QCD
|Research Area||Plasma & Particle Physics|
|Principal Investigator(s)||Dr. Dirk Pleiter|
Using the latest state-of-the-art 2+1 flavour lattice QCD simulations, at light quark masses down to the physical masses, we determine the form factors for the semi-leptonic decays of the K meson and strange octet baryons. Combining these form factors with experimental data we are able to accurately determine the CKM matrix element V_us, an essential parameter in constraining the Standard Model of particle physics.
